Fig. 2 shows different articles connected together according to my process.

Fig. 3 is a perspective view showing the use of a plurality of spraying and sanding devices.

a is the well known machine for automatically manufacturing staples from wire inserted into the machine and formed into staple or U-shape on the saddle d by means of the stamper c operated by the cam disc 17.

Each newly shaped staple will be removed from the shaping place by the sliding member to clear the space for the next staple, whereby a series of staples arranged close together will be formed on the saddle d. Said series of staples may be moved along spring blades or the like a plied to the saddle d, whereby a lateral pressure will be produced on the staples, so that the latter will be better pressed upon each other and dressed.

Moreover the speed of the forward movement of the staples on 'the saddle may be varied by means' of rotating friction rolls, whereby said staples will be moved forwardly with greater speed than that which is possible to obtain with the sliding member e.

g is a sand blast serving to roughenthe stapl in order to secure the perfect adherence of the subsequent metal sprayed upon the staples.

Theconnection of the staples is efiected by means of metal powder produced in the metal spraying pistol hand ejected through the nozzle 1',

said metal powder being brought into contact with the moving staples through a window It provided on the saddle d. Said window It is arranged with an intermediate space corresponding to the thickness of the staples on the saddle d either stationarily or adjustably. The opening of the window k may be such as to permit of metallizing the staples on their entire width. However said opening may also be such that a portion only of the width of the stapleswill be coated with metal. According to the discharge opening of the nozzle theconical jet will be stronger or weaker so that a very fine jet of metal dust may also be obtained, adapted to spray point or dash like connecting bridges upon the staples.

In the machine shown in Fig. 1 one spraying pistol and one sand blast are provided only. It will be obvious that a plurality of metal spraying devices operating from different sides, or pistols with a plurality of nozzles may be provided, so

that the strip of staples may be metallized simultaneously on all sides as shown in Fig. 3.

The staples I will be discharged from the machine in the shape of a unitary strip, from which a portion-p will be severed by means of a knife 19/ In my improved process unimportant feature resides in the fact that the metal sprayed upon the articles will immediately harden after being sprayed, whereby the strip of staples will not undergo any change.

According to the speed of the movement of the staples. below the spraying nozzles, the coating produced will be more or less thick, whereby it will be possible to vary the dimensions of the staples either totally or partly by simply adjusting the speed thereof.-

In Fig. 2, t is a strip of staples produced by means of my process and entirely coated with metal. M is a stick of sheet metal chippings, such as those used for mounting or inserting window-glasses into frames. u designates the connections of the chippings elected by means of metal sprayed upon them in the shape of a strip, whilst 11 designates needles united by pointlike connections of the type used in clamping or stitching tools for ataching together sheets of paper and the like.

Having now fully described my said invention, what I claim and desire to secure by Letters Patent, is:

1. A machine for manufacturing individual articles such as staples and the like and connecting said individual articles together, comprising in combination a machine for manufacturing said articles, a carrier onto which the articles are delivered in advance of the machine, a sand blast and a metal spraying pistol arranged immediately after the shaping place of said machine above the carrier supporting the finished articles, and means for feeding said articles forwardly on said carrier, substantially as set forth.

2. In a machine for manufacturing individual articles such as staples and connecting said articles together, the combination with a known machine for manufacturing the desired articles and a carrier supporting the finished articles in close arrangement, of a plurality of sand blasts above said carrier, a plurality of metal spraying pistols arranged after said sand blasts above said carrier, means for feeding the finished articles forwardly on said carrier below the sand blasts and metal spraying pistols, and meansfor dividing the strips or sticks of articles thus produced into sections of any desired length substantially as set forth.

3. In a machine for manufacturing individual articles suchas staples and connecting said articles together, thecombination with a known machine for manufacturing the desired articles and a carrier supporting the finished articles in close arrangement, of a plurality of said blasts above said carrier, a plurality of metal spraying pistols arranged after said sand blasts above said carrier, means for feeding the finished articles forwardly on said carrier, a knife mounted for swinging movement and operative in such movement to divide the articles and means for operating the knife.
